RAILROAD RAIL SUPPORTING STRUCTURE ".3

William N. Keurvorst, Verdun, Quebec, Canada Application February 4, 1933, Serial No. 655,174

20 Claims.

This invention has to do ingeneral with railroad rail supporting means, and specifically with means for anchoring a rail on a tie plate to restrain vertical andlongitudinal movement of V the rail with respect to the tie plate.

' 1 5 flange engaging spring arranged to be anchored to a tie plate, the said spring being of such formation that there is very little risk of breakage, inthe processof application to a rail, or

in useQg A still further object of the invention is to provide a rail anchoring spring embodying the aforesaid characteristics and advantages, which may be anchored to a tie plate by a simple anchoring clip, the said anchoring clip being so 2 designedthat a portion thereof is arranged to extend over the base flange of arail to limit "vertical movement of the rail with respect-to the tie plate. i

Another object is to provide simple and durable means to restrain endwise shifting of the rail engaging spring with respect to the tie plate.

The invention is further characterised by the provision of a novel form of tie plate and coacting rail anchoring means. f e

Other objects and advantages of the invention may be observed upon perusal of the following detailed description and the annexed drawing which illustrates one embodiment" of the in vention. o In the drawing: 1 i

Fig. 1 is a plan View showing a portion of a rail, a tie plate, and the application of the device of my invention thereto, and

Fig. 2 is an end sectional elevation-of the 5 structure shown in the aforesaid view.

Referring now to the drawing in detail, the numeral 10 designates a rail of standard form; 11 indicates the base flange thereof; and 12 and 13 the upright edges of the base flange. The 5 tie plate 14 includes the usual rail base supporting surface 15 andrail supporting shoulders 16 and 17 extending in parallel relation longitudinally of the tie plate. The said shoulders are so spaced that when the rail is mounted on the tie plate, a gap 18 is established atone side of the rail base flange between the upright edge 13 thereof and the shoulder 1'7, for receptionof the rail anchoring spring 19.

The rail anchoring spring 19 is of the semielliptical leaf type, with'the ends 20 and 21 formed in such Wise that when the spring is v mounted, as shown in Fig. 1, the said ends seat in the apertures 22 and 23 drilled or otherwise formed in the top face of the tie plate. The apertures are also formed so that portions of '65 the side wall 24 of the shoulder 17 are cut away to enable the ends 20 and 21 of the spring 19 to abut the walls of the said apertures, which walls establish abutment shoulders, the same being designated at 25 and 26. The spring 19 71 is of such formation and is so tensioned that when flexed and located in operative position as shown in Fig. 1, sufficient pressure is exerted by it to force the tie plate in the transverse direction of the rail and hold the upright face of the shoulder 16 against the upright face'12 of the rail base flange 11 in such-manner that a frictional bond is established between the rail 10 and the tie plate 14 at one side of the said rail, and between the rail base flange upright face '13 and the spring 19 at the other side of the rail.

The'spring 19 is held against vertical dis- 1 placement by the anchor clip 27. This clip is of substantially U-shape formation and includes one 3'5 30, the end 31 of which projects over the spring 19 and a portion of the rail base flange 11. The 9 anchor clip is notched at 32 at the sides thereof, and drift spikes 33, or the equivalent, seat in the said notches and extend through the apertures 34in the said tie plate, into the tie 35. The other side of the tie plate 14 may be secured to the tie "9' 35 in the usual manner, by one or more drift spikes 36, or the equivalent thereof.

To assemble the structure, the spring 19 is first flexed and positioned with a suitable flexing and inserting tool or device, so that it lies between the upright face 13 of the rail base flange and the face 24 of the shoulder 1'7, with the ends 20 and 21 thereof seated in the apertures 22 and 23 in position to abut either of the abutment shoulders 25 and 26. The anchor clip 2'? is then driven, in the transverse direction of the tie plate 14, to the position illustrated, followingwhich the drift spikes are driven into the'tie 35.

The principal function of the structure is to restrain longitudinal shifting of the rail when the latter is subjected to endwise thrust. To counteract the tendency for the rail to creep in its longitudinal direction, an intense frictional bond is established between the side wall of the shoulder 16 and the upright face 12 of the rail base flange, at one side of the rail, and between the upright face 13 of the rail base flange and the spring 19 at the other side of the rail. A further feature is to provide means to establish positive anchoring of the spring 19 so that it can not be accidentally dislodged from its operative position. This is accomplished by location of the ends 20 and 21 of the spring in the apertures 22 and 23 in position to abut the abutment shoulders 25 and 26 established by said apertures. In the event of the rather remote possibility of spring breakage, a broken portion of the spring can not work in an endwise direction out of the gap 18 unless its angular end is also broken off. This obliterates the possibility of the rail shifting transversely towards the shoulder 17 in the event of spring breakage.

A still further feature of the device of my invention resides in the peculiar formation of the anchor clip 27 and its mounting arrangement. The anchor clip, due to its U-shaped formation and form of anchoring against the under side of the tie plate, must flex or open up to permit upward movement of a rail a distance greater than the clearance space provided, if any, between the rail base flange and the overlying end 31 of the arm 30. Thus a resilient anchoring means is provided to hold the rail down on the tie plate, which affords many advantages over the well known spiking arrangement. The two spikes 33 positively limit movement of the anchor clip 2'? transversely or longitudinally of the tie plate, wherefore the said spikes must be worked very loose or completely removed before the spring 19 can be accidentally dislodged from its operative position.
